Definitions
- the invention relates to a trunk for a power converter for in particular to equip a traction chain of a railway vehicle.
- the maximum allowable current is dependent on the amount of heat that the device is able to evacuate.
- the most common solution used on railway vehicles to ensure the cooling of the power modules used in the converters consists of attach an aluminum radiator, equipped with cooling fins, against each different bases of power modules, all the different modules equipped with their cooling radiator being placed in a safe located under the vehicle and open on the sides to allow the circulation of a flow of air, especially when moving the vehicle.
- the purpose of the present invention is therefore to propose a box for modules power electronics which ensures, with great reliability, an excellent cooling power components in a small footprint, thus reducing the number of electronic power modules necessary for the realization of an installation of the inverter type in a chain of railway vehicle traction.
- the subject of the invention is a trunk for a power converter, intended in particular to equip a traction chain of a railway vehicle, comprising electronic power modules consisting of one or more power semiconductor components mounted on a substrate, characterized in that it comprises a base comprising a double-walled lower panel presenting an inner wall, disposed towards the inside of the trunk, on which is contiguous to the least one substrate supporting a power component, the lower panel extending by at least two double-walled side panels whose walls are cooled by means of cooling fins, and that both walls of the bottom panel delimit a hollow volume partially filled by a coolant and containing a permeable material, thermally conductive, realizing a thermal bridge between the two walls.
- FIG. 1 represents a box for a power converter intended to equip a traction chain of a subway.
- the trunk comprises a base 1 provided with a panel lower 3 double wall 3a and 3b extending by two side panels 2 extending perpendicular to the bottom panel 3.
- the two side panels 2 are also double-walled 2a and 2b and are symmetrical with respect to the plane longitudinal passing through the center of the trunk parallel to the side panels 2.
- the base 1 is preferably made of metal material good conductor heat.
- the lower panel 3 supports on its inner wall 3a, oriented towards the inside of the box, power modules 4 for the operation of the inverter, each power module consisting mainly of one or more components of type IGBT power mounted on conductive tracks made on a substrate 5 made of electrically insulating material and good conductor of heat, for example aluminum nitride AlN, the underside of the substrate 5 being contiguous directly to the inner wall 3a and being welded to the base 1 by means of a solder.
- a substrate 5 made of electrically insulating material and good conductor of heat, for example aluminum nitride AlN
- the side panels 2 support on their inner wall 2a components 6 which are preferably passive components, for example type capacitor, having the distinction of being less dissipative than the integrated power components in modules 4 arranged on the panel bottom 3 of the base 1.
- components 6 which are preferably passive components, for example type capacitor, having the distinction of being less dissipative than the integrated power components in modules 4 arranged on the panel bottom 3 of the base 1.
- each side panel 2 is accordion-shaped so as to forming multiple cooling fins, arranged perpendicular to the side panel 2, ensuring a heat exchange with the ambient air. These fins of cooling extend parallel to the axial direction of the subway so as to be swept by a stream of air when moving the subway.
- the box is closed by a lid 7 having a shape complementary to the base 1 and providing protection against the external aggressions of different 4.6 components located in the trunk.
- the lower panel 3 has a hollow volume disposed between the two walls 3a and 3b, which is filled with a permeable material 8, such as copper foam, providing strong conduction between the inner wall 3a and the outer wall 3b of the lower panel 3.
- the lower panel 3 also contains a coolant, such as water, which partially filled the pores of the copper foam 8, the liquid level being dashed line in FIG. 2.
- the permeable material 8 may also consist of a stack grids, for example copper or aluminum, providing the same function of thermal bridge between the inner wall 3a and the outer wall 3b.
- the base 1 thus formed constitutes a two-phase system in which the liquid contained in copper foam 8 evaporates through the pores during the rise of temperature caused by the operation of the various components of power, the vapor thus released traveling through the side panels 2 and condensing on the outer wall 2b, at the level of the cooling fins.
- the condensed and cooled liquid then falls back into the copper 8 panel foam lower 3 and contributes to the cooling of the power modules arranged on the inner wall 3a of the lower panel 3.
- the passive components, arranged on the side panels 2, are themselves cooled by conduction through the inner wall 2a of the side panels 2.
- FIGS. 3 and 4 show an alternative embodiment of the box according to the invention in which the lower panel 3 of the base has an outer wall 3b accordion forming multiple fins enhancing cooling efficiency.
- the side panels 2 of the base 1, the cover 7, the implantation of the different power modules 4 and passive components 6 remain unchanged by relative to the embodiment previously described.
- the lower panel 3 is hollow and is filled with a copper mouse 8 coming to fill the inside of the cooling fins as well as the space separating the inner wall 3a from the outer wall 3b in order to make a bridge thermal between the two walls 3a and 3b.
- the porous material 8 is partially filled with a liquid refrigerant such as water, the liquid level being shown in dotted line on the figure 4.
- Such a power converter box constitutes a two-phase system operating in a similar way to the box described in Figures 1 and 2, the cooling of power components being further enhanced by the surface more important exchange.
- FIG. 5 represents an alternative embodiment of the trunk of FIG. which the outer walls 2b and 3b of the side panels 2 and lower 3 are planes and the cooling fins are reported, for example by welding.
- the operation of such a trunk for power converter remains unchanged by compared to the box described in FIGS. 3 and 4.
- Such an embodiment variant presents the advantage of simplifying the manufacture of the safe.
- the chests for power converter according to the invention have the advantage to ensure excellent protection of the power modules against the aggressions thanks to the confinement of these in the trunk while ensuring a very efficient cooling.
- the cooling provided by such chests also remains effective when the vehicle is stopped by evaporation of the coolant in the bottom panel of the base.
